10.15 Scheme->C interface

Most of the C functions interfacing with Guile/Scheme used in LilyPond
are described in the API Reference of the
GUILE Reference Manual.

The remaining functions are defined in ‘lily/lily-guile.cc’,
‘lily/include/lily-guile.hh’ and
‘lily/include/lily-guile-macros.hh’.
Although their names are meaningful there’s a few things you should know
about them.
